A furnace discharge device for a box-type resistance furnace

Abstract

The invention provides a discharge device of a box type resistance furnace. The discharge device comprises a structure which is shaped like a Chinese character tian and formed by nine columns and reinforcing ribs; a frame is divided into a front portion and a rear portion; the rear portion comprises an inclined plate which is arranged on the columns; the front portion comprises an arc-shaped guide plate; the bottom of the arc-shaped guide plate is provided with a rotatable device which is fixed between the lower middle column and the middle column; the lower right column and the right middle column are provided with a square pipe; the lower left column and the left middle column are provided with a limiting frame; the left side of the front portion is provided with an adapting plate which is provided with a limiting pipe; a rotating pin pivots in the limiting pipe; the rotating pin and a conical bucket are fixed; one end of an extension spring is fixed on the conical bucket; the other end of the extension spring is connected onto the left column. According to the discharge device of the box type resistance furnace, circular bar materials can be changed from the horizontal direction to the vertical direction without increasing the additional power and accordingly the labor is reduced, the cost is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a furnace tapping device, in particular to a furnace tapping device involving relatively large mass round bars in a box-type resistance furnace. Background technique [0002] The box-type resistance furnace is one of the main equipments for billet heating in thermal processing. It has good furnace temperature uniformity and billet temperature consistency, and the degree of oxidation and decarburization on the surface of the billet after heating is small. [0003] Originally, when the round bar was released from the box-type resistance furnace, the first person needed the first person to hook the round bar out of the box-type resistance furnace with an iron rod and roll it down to the receiving platform, and the second person used pliers to pull the round bar out of the box-type resistance furnace. One end is clamped, and the other two use an iron rod to lift one end of the round bar to stand on the receiving platform. A total ...

AI Technical Summary

Problems solved by technology

A total of 4 people are required to work together at the furnace door, and the production efficiency is low

Not only is the labor intensity high, but the billet rolls onto the unobstructed receiving platform, and may roll down to the cement floor, causing the cement floor to burst, posing a safety hazard. In addition, the temperature of the round bar falling on the ground is also greatly reduced. Affect the subsequent die forging
